Plot

The series follows Suuna Kuruma, a high school student who has just moved into a new dorm. Upon arriving at her new room, she discovers a girl, Ruka Hamanasu, flirting with another girl. Suuna is surprised to see this happen, to which Ruka claims that they were not going out. She claims the other girl was her sefure (セフレ), which she says is short for "semi-friend". As Suuna has no other friends, Ruka offers to be her semi-friend.

Characters

A high school student and Ruka's roommate. She has a very shy personality and thus had been unable to make any friends prior to meeting Ruka. She is conscious of her name as its kanji is hard to read.

Ruka Hamanasu (浜薔薇 輝子, Hamanasu Ruka)

Suuna's roommate, whom she saw flirting with another girl during their first meeting. She claims the other girl is her sefure, but as Suuna is unfamiliar with the term, she claims it is short for "semi-friend". She has a gyaru personality.
